MOBI page breaks become real chapters in the EPUB table of contents, so navigating a converted book feels native.

No account, no sign-up, no file size cap. Your conversion is instant and costs nothing.
About MOBI to EPUB Conversion
MOBI is the proprietary e-book format that older Amazon Kindle devices used, built on the PalmDOC compression scheme inside a PDB container. Because it was designed for a single vendor, many modern readers no longer support it. EPUB is the open, universal e-book standard that every modern reader understands. AnyDocFlow's MOBI to EPUB converter reads the PalmDOC-compressed text, decompresses it locally, pulls the title, author, language and cover from the MOBI metadata (EXTH), splits the book into chapters, and rebuilds it as a clean, standards-compliant EPUB3. The result is a reflowable, device-independent e-book you can open anywhere — no account, no uploads, and no waiting.
How to Convert MOBI to EPUB
Convert your e-book in three simple steps — no sign-up needed.
Choose your files
Drag and drop one or more .mobi e-books onto the converter, or click to browse your computer.
Conversion starts automatically
Each file is parsed and rebuilt locally with live per-file progress — no button to press.
Grab your EPUBs
Every finished book appears in the list below the dropzone — download it directly, or grab all your converted books as a single ZIP.
Notes & Limitations
DRM-protected or encrypted e-books cannot be converted — please make sure you have the legal right to convert a file you own. The converter reads the MOBI format; other file types will be rejected. The output is a reflowable text-based EPUB — fixed-layout MOBI features are not preserved. Everything runs locally, so no file ever leaves your device.
